HINGE.

Application filed April 1 The object of my invention is to produce an efiicient hinge structure which may be readily applied to two adjacent table leaves.

The accompanying drawings illustrate my invention.

Fig. 1 is an under plan of my improved hinge in place; Fig. 2 a section on line 2-2 of Fig. 1 and Fig. 3 a section on line 3-3 of Fig. 1, and Fig. 4 a.- section like 3 in folded position.

In the drawings 10, 10 indicate two sheet metal butt members the ends 11 of which are upturned. Pivoted at 12 to each upturned portion 11 is an L-shaped lever 13 to 15 the outer end of which is pivoted, at 1 1, the outer end of an L-shaped lever 15 pivoted at 16 to an upturned endll of the butt 10. Each, pair of levers 13, at their crossing point, is connected by pivot 17.

members 10 are identical and of the same length and the levers are so associated therewith, as clearly shown in Fig. 1, that one butt is longitudinally oii'set relative to the other by an amount equal to the thickness of the connecting levers. There is no need therefore for any oflsetting of any portions of the connecting levers.

As will be noticed in Fig. 1, the two butt serial in. 180,089.

The upturned ends 11, and the connected lengths, are let into the under surfaces of so the table leaves 20, 20 in gaines: or grooves 21, and the hinge secured in place by screws 22 passing through the butts into the under surfaces of the leaves. 7

I claim as my invention: c A. hinge comprising two sheet metal butts having their two ends upturned at right angles to their intermediate portions and connected in pairs by two tour-link sets of levers, each of said sets comprising two pairs of L-shaped links, each of said links comprising one long arm and vone short arm and the short arms or all links pivoted to the upturned ends of the butts, the longer arms of adjacent links-of each set crossing each other and pivotally connected together at a point intermediate the lengths of said long arm and said longarms pivotally connected at their tips with the tips of the long arms of the other link of the adjacent pair. In witness whereof, I have hereunto set my hand at Wabash, Indiana, this 19th day of March, A. 1). one thousand nine hundred and twenty-seven i FREDERICK B, WALTER.
